Compressor runs noticeably longer than the fuel pump. The longer it was sitting and the more load was added the longer the compressor will run.

cadillacjeff7777 Posted April 25, 2011 Report Share Posted April 25, 2011 Are you questioning whether you have the feature or not? You can look at the shocks/struts and see if they have the air bags on them. 2008 DTS Link to comment Share on other sites More sharing options...

He should have the feature. Probably blown fuse, broken wire or bad or intentionally disabled compressor.
